CAP-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 493,525, dated March14, 1893.

Application filed August 3, 1892.

To all whom it may concern.-

Be it known that I, HENRY SOHAAKE, a citizen of the United States.residing at San Francisco, in the county of San Francisco, and State ofCalifornia, have invented certain new and useful Improvements in Gap-Making Machines; and I do hereby declare the following to be a full,clear, and exact description of said invention, such as will enableothers skilled in the art to which it most nearly appertains to make,use, and practice the same.

My invention has relation to certain new and useful cap making machinesfor cans, which consists in the arrangement of parts and details ofconstruction as will be hereinafter more fully set forth in thedrawings, described and pointed out in the specification.

The object of my invention is to provide a continuously operating capmaking machine, wherein shall be embodied or involved two sets ofrotating dies, that is to say, an upper and lower set, one being maleand the other female, which shall receive the sheet metal from which thecap is to be stamped, at such a point as to bring the operators fingersor hands out of contact or probable contact with the upwardly movingdie, thereby completely obviating the liability of the hand beingmashed, as is the ease with such machines as are now in use, and toprovide for the stamping of the cap at a predetermined distance from theoperator, and further, in allowing of the automatic stamping anddischarge of the cap upon the continuous movement of the machine.

Referring to the drawings forming a part of this application, whereinsimilar letters and figures of reference are used to denotecorresponding parts throughout the entire specification and severalviews, Figure 1 is a side elevation of the entire machine; the casing offrame thereof being partly broken away; Fig. 2,a top plan theroof; Fig.3, a front elevation of Fig. 1; Fig. 4., an enlarged, broken, detailView, showing one of the plungers for operating the female die, and Fig.5, a top plan of Fig. 4.

The letter A, is used to indicatethe frame Serial No. 442,090. (Nomodel.)

of my machine, which is constructed hollow, and within which works andis secured within suitable bearings, transverse shaft B, to outerprojecting end of which is secured belt pulley B, by means of which saidshaft is given rotation through the medium of any suitable mechanism.Upon this shaft is rigidly secured, within hollow base of frame A, bevelgear 0, which rotates therewith and meshes with larger bevel gear 0,connected or secured to the lower end of vertical shaft D, which passesthrough hollow uprightportion of frame A, as shown in Fig. 1. This shaftprojects somewhat beyond hollow frame and has secured rigidly thereto,sleeve D, the lower end of which rests on top of hollow frame A.Inasmuch as said sleeve is rigidly secured to the vertical shaft bybeing keyed, or otherwise, it is obvious that the same rotatestherewith. From upper and lower ends of the sleeve D, project laterallyextending arms E, 7c E, each of which terminates in an enlarged head, EE provided with a central vertical opening, through which work theplunger rods. Within upper set of heads, E work plunger rods F, thelower end of each being enlarged so as to form the male or stamping dieF. These plungers, between under face of enlarged head E and upper faceof die F,

I surround by a heavy spring F in order to make the die spring-actuated,said rods being held in position by means of pins f. However, if sodesired, springs F may be dispensed with and rods F,.be rigidly securedwithin heads E although this feature of the device is immaterial,inasmuch as it depends S5 greatly upon the relative height to which thefemale dies, hereinafter set forth, are lifted during their course ofrotation.

Through the central opening formed in the heads E work plunger rods H,the upper ends of which rods are somewhat enlarged, as shown at H, andsaid rods and heads have the central opening h, formed therethrough, theopening, or open portion of the head being considerably enlarged, asshown, consequently forming a space It, and the inner walls of the headI further cut away so as to provide the shoulder k and seat 71 for thecap when depressed and formed by the male die, as hereinafter set forth.Within the enlarged port-ion, W, of the head H, works what I term thedie bottom H secured to the rod H which works through opening h, formedin the plunger rod H.

The lower end of plunger rod H, is bifurcated, and within bifurcatedportion is located roll I. To lower end of rod H is secured pin 1, whichprojects laterally therefrom, and through slotted portion of plunger rodH, as fully shown in Fig. 4. The die bottom H is provided with openings11, within which are located spring-actuated lugs 11'. When the bottomis raised or lifted, as will be hereinafter set forth, said projectionsor lugs will extend above the level of the female die, in order to raisethe stamped cap so as to clear pin t This pin is for the purpose ofmaking a central perforation in the cap 1 as shownat Fig. 4, for thepurpose of providing vent opening to the cap.

To one side of the frameA,is secured track way K, which inclinesupwardly from the points 1 to 2, and descends from 2 to 3, as fully setforth in Fig. 3. As the heads E are carried or rotated by means of thevertical shaft D, the roll I, of plunger rod H, travels upon thetrackway K, and inasmuch as said traekway gradually inclines upwardly,it is obvious that plunger rod H, and the enlarged head thereof aregradually raised until contact is made with the male die, and inasmuchas the sheet of metal rests upon the enlarged head of the plunger, whichenlarged head, as before stated, forms the female die, it is obviousthat the metal is forced within the female die until the cap is givenits proper shape. As the heads continue their rotary travel, the roll Iruns upon the gradually descending portion of the trackway, consequentlylowering the plunger rods until the femaledie has been brought to itsnormal position. It will thus be seen that the female die is raised andlowered automatically with the continuous rotary travel of the heads EInasmuch as the male dies are carried by the heads E sim ultaneouslywith the female dies, it is obvious that as the female die rises,it ofnecessity must contact with the male die. I also secure to the frame A,the cam K, and upon this cam, the pin 1, of rod H travels, and as thesame is inclined, it is obvious that travel thereon gradually lifts saidrod and forces the bottom of female die upwardly to the distance shownin Fig. 4. As the bottom rises, the spring-actuated lugs are carriedabove the level of the female die, and serve to lift the stamped capfrom within the seat thereof, and above the air vent projection or pin1?. From the frame A projects the rightangled bracket K to which issecured at the upper end thereof, the inwardly projecting, flexiblestrip L. This strip may be formed of thin metal, canvas, or any othermaterial suitable for the purpose, and is adapted to move the stampedcap from ofi the spring-actuated projection of the female die during theline of rotation of said die. As caps are moved from off saidprojection, they fall into the chute L, secured in any suitable mannerto the frame A, as shown in Fig. 3. As the pin 1', moves from off cam K,rod H drops to its normal position, consequently lowers the end offemale die, and as said die is carried beyond the flexible strip L, itis in position to receive another sheet of metal, which is likewisecarried around with the female die and stamped to its proper shapeduring the rotation of the machine.

I provide a number of male dies in order to obviate undue wear, whichwould result by use of only one male die; consequently inmy device, Iprovide a male die foreach female die, and inasmuch as the male diesrotate with the female dies, it is obvious that only such wear resultsthereto as is caused by the movement of the female die correspondingthereto.

Inasmuch as the sheet metal is fed to my device at a point considerablybeyond the stamping point, it is obvious that no danger whatever is runby the operator of having his hands hurt by feeding directly between theupwardly moving dies, which does result in the use of the presentmachines, which are not continuous in their movement, but intermittent,and are operated through the medium of the foot.

Having thus described my invention, what I claim as new, and desire tosecure protection in by Letters Patent of the United States, 1s-

.1. In a cap making machine for cans, the combination with a set ofvertically movable male dies of a set of female dies, locatedthereunder, mechanism for synchronously rotating the male and femaledies, and, during the operation thereof, raising the female dies, and ofthe flexible wiping strip for moving the stamped cap into dischargechute, as and for the purpose set forth.

2. In a cap making machine for cans, the combination with the female diethereof, of the movable bottom located therein, and of thespring-actuated lugs secured within the movable bottom, and of themechanism for raising and lowering the movable bottom during therotation of the female die, as and for the purpose set forth.

3. In a cap making machine, thecombination with the male dies, of thefemale dies, mechanism for rotating said dies and during rotationthereof, raising and lowering the female dies, of the movable bottomlocated within the female dies,of the spring-actuated lugs securedtherein, and of cam for raising said bottom during travel of the dies.

4. In a cap machine, the combination with the female dies, of themovable bottoms,

IIO

spring-actuated lugs secured therein, and of the cam adapted to raisesaid bottom and lugs during travel of female die.

5. In a cap making machine, the combination with the female die providedwith a movable bottom, cam for raising said bottom, spring-actuated lugssecured within the movable bottom, said lugs adapted to project beyondlevel of female the when the bottom is raised, andof the flexible rod orstrip for 10 moving the cap from 01f the female die during the travelthereof.

In testimony whereof I affix my signature in presence of two witnesses.
